Samsung is rolling out its major One UI 9 Watch software update (built on Wear OS 7) to the Galaxy Watch 8 series and the rugged Galaxy Watch Ultra. This upgrade marks the biggest software shift of the year for Samsung’s smartwatch lineup, bringing a fresher interface, smoother animations, and deeper health integrations.
Fresh Look for Health Data and Charts

The user interface looks much cleaner now. Samsung redesigned how health data appears on the screen. Important details like your sleep score and daily vital signs now use clearer charts that fit the round screen perfectly.
All health numbers use matching colors. This makes it very easy to see at a quick glance if your health numbers are better or worse than usual. The Samsung Health app on your phone also gets new interactive charts and custom options to match.
Smoother Animations and Quick Tiles
When the watch measures things like your heart rate, stress levels, or body fat, you will see new and smoother animations.
Samsung also added new quick-access tiles. These tiles let you open tools much faster, such as the built-in sleep coach.
Better Compass and Camera Tools
The Compass app gets a helpful new feature. You can now save important spots, like where you parked your car, as a waypoint with just one tap. The watch will then help you navigate right back to it.
If you use your watch to control your phone camera, you will find new shooting modes to make taking pictures easier.
Easy Ways to Customize Watch Faces
The Samsung Wearable app on your phone gets a makeover too. It is now much easier to browse, choose, and change your watch faces.
Right now, the update is starting to roll out for users in South Korea and the United States who took part in the beta test. It will reach everyone else around the world in the next few weeks.
